Measurements of Oxygenated Volatile Organic Compounds Over the Ocean
Abstract
The influence of the ocean on the regional and global budgets of select oxygenated volatile organic compounds (OVOCs) is investigated. Measurements of OVOCs were made on board the NCAR C-130 in addition to a comprehensive suite of VOCs during the NASA INTEX-B research program with the NCAR Trace Organic Gas Analyzer (TOGA) and the NCAR PTR-MS. Ground-based measurements were made at Thompson Farm in Durham, NH and Appledore Island, ME by the University of New Hampshire's PTR-MS. Results from the aircraft- and ground-based measurements are compared and discussed in terms of recent published results and are interpreted with the aid of air-sea exchange models and a global 3-D model, MOZART-4. Markedly different behavior of the semi-soluble gases compared to less-soluble compounds is observed; implications for OVOC regional and global budgets are discussed.
